I recently received a few EX and Mega - EX Pokemon cards that I am suspicious are fake.
The holographic part covers the entire card, and isn't detailed, it just makes the whole thing shine.
The colors seem a bit off.
Not only the front but the back is waxy. It doesn't feel like other EX cards I have.
The cards seem off-center.
There is not a line running through the center of the card if you look at the edge.
Are these fake?
(The cards are Gardevoir-EX, M Diancie-EX, M Manectric-EX, and Lunala-GX.)

Well, I can't really answer that without a picture of the front and back of each card, if you can upload them, I will be able to tell you. On the other hand, they sound fake to me but I can't be 100% sure on that one.
